“Used this BCG in an Aero M5E1 308 build and experienced multiple double feeds. Added a second o-ring to the extractor and it's been perfect ever since. The nitride finish makes cleanup much easier than a phosphate BCG. For the price I guess I'm I'm with the extractor issues, but this seems like something they should address as I see another reviewer experienced the same problem.”
“Put the bcg in an Aero 6.5 build all Aero parts except bcg
Had failure to extract issues
I took the extractor off and added a second o-ring to the extractor seems to be ok
If I would buy it again I would get the Aero”
